The DTNO.1 DT Ultra 2 is a budget smartwatch built to run Android apps as well as pair with a phone over Bluetooth. That makes it more like a small Android wrist computer than a conventional fitness watch—but its battery life, water rating, app compatibility and health features are less certain than the headline specifications suggest. It may suit a technically confident buyer who wants apps and an Ultra-inspired design; it is a poor choice if dependable sports tracking, health readings or seamless phone integration are the priority.
What is the DT Ultra 2?
DTNO.1 lists the DT Ultra 2 as a fashion smartwatch. Its defining feature is a dual-system design: an Android mode for apps and Wi-Fi-connected functions, and a Bluetooth mode for connecting to a smartphone. The manufacturer advertises a large AMOLED screen, phone calls, GPS-related functions and app support. Those are listed capabilities, not independent confirmation that every app, sensor or connection works reliably on every unit. DTNO.1’s product catalog includes several similarly named watches, so confirm the maker and exact model before ordering.
The watch has a rectangular, ruggedized look associated with the Apple Watch Ultra, but it is not an Apple product or a direct Apple Watch equivalent. A Notebookcheck description also notes the visual similarity and Android-watch positioning.
DT Ultra 2 specifications: official listings disagree
DTNO.1’s product pages do not give a single consistent specification set. The figures below are manufacturer claims; check the exact seller listing and unit rather than assuming every batch has the same hardware.

| Specification | What official listings report |
|---|---|
| Chipset | MTK6739 plus 8763 on the DTNO.1 product page; a regional listing names MTK6739. |
| Memory and storage | 2GB RAM and 16GB storage, listed by the global store. |
| Display | 2.06-inch AMOLED, 410×502 on one official page; 2.1-inch AMOLED, 420×485 on the regional listing. |
| Wireless and connectivity | Bluetooth 5.3 and Wi-Fi are listed by DTNO.1; the global store also advertises GPS-related functions. |
| Battery | 880mAh, according to official listings. The regional page claims five to six days of normal use and 25–35 days standby; these figures are not a verified result for full Android use. |
| Charging | Magnetic charging. One official page says under 3.5 hours; the regional listing says about two hours. |
| Water resistance | IP67 on the product page; IP68 on the regional listing. |
| Case and weight | 49×43×11.5mm and 46g on DTNO.1’s product information. |

What can it do?
Android apps, Wi-Fi and Google Play
The global store advertises Google Play support, while DTNO.1’s other product information describes Android apps and internet-connected functions. This does not establish that Google Play Services are certified, that every app is compatible with the watch’s screen and hardware, or that app updates and account sign-in work normally on every firmware version. Before buying, ask whether Play is preinstalled and working on the exact unit, which Android version it runs, and whether the seller provides firmware recovery files.
Bluetooth calls and phone connection
DTNO.1 lists Bluetooth 5.3, calling-related functions, a microphone and speaker. The WearPro app is part of the intended phone-connected setup. A phone’s notifications, contacts and health synchronization may depend on the app and Bluetooth permissions; a claim of broad phone compatibility does not establish that all features work equally on Android and iPhone.
GPS, maps and media
The manufacturer advertises GPS or map-location functions, music and video playback. Its public specifications do not clearly identify the GPS chipset or satellite systems, or establish location accuracy, route-recording behavior, or whether location works independently of a phone or Wi-Fi. Treat GPS as an advertised feature—not proof of dependable standalone sports tracking.

Health and wellness functions
DTNO.1 lists heart-rate monitoring and health-management functions through WearPro. The available product information does not provide independent clinical validation. Treat readings as general wellness estimates, not medical measurements; do not rely on them for diagnosis, treatment choices or emergency monitoring. The listed functions do not establish reliable blood pressure, blood glucose, ECG, blood oxygen, sleep-stage, calorie or heart-rate-zone measurements.

Battery life depends on how you use it
The regional DTNO.1 listing claims five to six days of normal use and 25–35 days on standby, but does not define the operating mode and workload behind “normal use.” The global store cautions that battery life differs substantially from that of a conventional Bluetooth smartwatch, and customer reviews on that store report around a day or less in some heavier-use situations. These reports are not a controlled test, but they make the long endurance claim a risky assumption for Android-mode use.
Using Wi-Fi, GPS, calls, video, a bright screen, frequent notifications or always-on display behavior can increase power use. Bluetooth mode is the more sensible choice for routine phone-connected use if you do not need Android apps; turn off unneeded radios and background activity, lower brightness and screen timeout, and charge before extended calls or GPS use. DTNO.1 says the battery is not replaceable, which also limits serviceability if it degrades.
Does it work with Android phones and iPhones?
The regional official listing claims compatibility with Android 4.4 or later and iOS 10.0 or later. That is a broad compatibility claim, not a feature-by-feature guarantee. Bluetooth pairing is distinct from notifications, calling, health-data synchronization and message replies; app installation directly on the watch is a separate Android-mode function. The available product information does not establish parity across those functions on iPhone, or seamless Apple Health and Apple ecosystem integration.

There is no single consistent answer in DTNO.1’s own specifications: one page says IP67 and another says IP68. Ask the seller which rating applies to the exact unit and request documentation for that batch. Even a stated IP rating describes protection under specified conditions; it is not blanket permission for swimming, diving, hot showers, salt water or exposure to soap. Do not use it as a dive computer.

How to avoid buying the wrong “DT Ultra 2”
Marketplace titles can combine “DT Ultra 2,” “Vwar,” “Pro Max,” “Playstore” and other terms. A third-party manual listing uses the Vwar DT Ultra 2 name, while marketplace listings also vary their wording. That is not enough to establish that those products are identical to DTNO.1’s model. Compare the manufacturer, chipset, display resolution, dimensions and companion app—not just the listing title.
Before placing an order, get clear answers to these questions:
- Is the maker DTNO.1, and what exact model or hardware batch will ship?
- Which Android version is installed? Is Google Play preinstalled and functional, and are Google Play Services certified?
- Can GPS record a route without the phone, and which features work with an iPhone?
- Is this unit rated IP67 or IP68, and what documentation covers that rating?
- What are the return address, warranty period and available firmware recovery options?
- Is the watch in stock, and what is the final checkout cost including shipping and tax?
The DTNO.1 global store page has displayed the watch as sold out while showing a promotional price, so treat price and availability as changeable and confirm both at checkout.
Do these 3 things before closing this tab:

It may suit you if
- You want an inexpensive watch with a large screen and an Ultra-inspired appearance.
- You specifically want to experiment with Android apps on a watch and are comfortable troubleshooting app or firmware issues.
- You are willing to manage charging and verify the seller’s claims before relying on a feature.
Look elsewhere if
- You need dependable GPS for running or cycling, or health measurements you can use for medical decisions.
- You intend to swim or need a clearly documented water-use rating.
- You expect long battery life, polished iPhone integration, long-term software updates or established repair support.
- You want a low-maintenance smartwatch experience rather than a small Android device that may need app and permission management.
For those priorities, choose by use case: a mainstream Wear OS watch for a more established Android-watch ecosystem, an Apple Watch for iPhone integration, a sports-focused watch for training, or a basic Bluetooth smartwatch if simplicity and endurance matter more than installing apps. These are categories, not claims that a particular model has been compared or tested here.
